[0036] If the terms "first" and "second" are used only to distinguish technical features, they should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0037] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0038] Reference Figure 1 , Figure 2 and Figure 8 A cleaning machine cover structure includes a main housing 100 and a cover assembly 200. The upper part of the main housing 100 is provided with an upwardly extending ear plate portion 110. The cover assembly 200 is provided with a corresponding slot 201 for inserting the ear plate portion 110. The cover assembly 200 has a connecting cavity 202 and a rotating shaft 210 is provided in the connecting cavity 202. The ear plate portion 110 can extend into the connecting cavity 202 through the slot 201 and be rotatably connected to the rotating shaft 210. The slot 201 can avoid the rotation of the ear plate portion 110 relative to the rotating shaft 210, so that the cover assembly 200 can rotate relative to the main housing 100.

[0039] Understandably, such as Figure 1 , Figure 2 , Figure 8 and Figure 10As shown, the upper right side of the main housing 100 is provided with two upwardly extending ear plates 110, and the upper cover assembly 200 is provided with two corresponding slots 201. The lower or right side of the slots 201 are open structures so that the ear plates 110 can be inserted and their rotation relative to the pivot 210 can be avoided. In use, the ear plate portion 110 extends into the connecting inner cavity 202 through the slot 201 and is rotatably connected to the rotating shaft 210 in the connecting inner cavity 202, forming a rotatable connection structure between the main housing 100 and the upper cover assembly 200. When the ear plate portion 110 rotates relative to the rotating shaft 210, the slot 201 can avoid the ear plate portion 110, so that the upper cover assembly 200 can rotate relative to the main housing 100. The above structure is simple and reasonable. By setting the slot 201 and the connecting inner cavity 202, the rotatable connection structure between the main housing 100 and the upper cover assembly 200 is hidden in the connecting inner cavity 202, which is beneficial to improving the appearance of the cleaning machine and can better protect the rotatable connection structure, reduce the possibility of oxidation and corrosion of the rotatable connection structure, and improve its reliability and service life.

[0040] In practical applications, the specific structures of the main housing 100 and the upper cover assembly 200 can be set according to actual usage needs, and will not be described in detail here. They will be explained in detail below.

[0041] In some embodiments, a torsion spring 310 is provided in the connecting cavity 202. The torsion spring 310 is sleeved on the rotating shaft 210 and one end of the torsion spring 310 is fixedly connected to the upper cover assembly 200. The other end of the torsion spring 310 is engaged with the ear plate portion 110 to act on the upper cover assembly 200 and make the upper cover assembly 200 have a tendency to rotate and open relative to the main housing 100.

[0042] Understandably, such as Figure 2 , Figure 3 and Figure 8 As shown, the ear plate portion 110 has a snap-fit ​​notch 111. A torsion spring 310 is sleeved on the rotating shaft 210, with one end fixedly connected to the upper cover assembly 200 and the other end snapped into the snap-fit ​​notch 111 of the ear plate portion 110. The torsion spring 310 acts on the upper cover assembly 200, causing the upper cover assembly 200 to have a tendency to rotate and open relative to the main housing 100, thereby facilitating the rotation and opening of the upper cover assembly 200 and making it convenient to use. In actual applications, the torsion spring 310 can be set according to the actual usage requirements.

[0043] In some embodiments, a hovering member 220 is provided in the connecting cavity 202. When the upper cover assembly 200 rotates relative to the main housing 100, the hovering member 220 can restrict the upper cover assembly 200 to a preset position.

[0044] Understandably, such as Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, by setting the hovering component 220, during the rotation of the upper cover assembly 200 relative to the main housing 100, the hovering component 220 restricts the upper cover assembly 200 to a preset position, thereby enabling the upper cover assembly 200 to be suspended at the preset position. This allows the upper cover assembly 200 to have multiple opening degrees, making it convenient for users to select and use according to their needs, thus improving its applicability. In actual applications, the specific structure of the hovering component 220 can be set according to actual usage needs, and will not be described in detail here, but will be explained in detail below.

[0045] In some embodiments, the ear plate portion 110 is provided with a limiting post portion 311, and the hovering member 220 is provided with a guide groove 221 for the limiting post portion 311 to extend into. The guide groove 221 is provided with a constriction position 222. When the upper cover assembly 200 rotates relative to the main housing 100, the limiting post portion 311 can move along the guide groove 221. The limiting post portion 311 can move to the constriction position 222 and abut against the wall of the guide groove 221 at the constriction position 222.

[0046] Understandably, such as Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the hovering member 220 is fixedly installed in the connecting inner cavity 202. The torsion spring 310 is engaged with a limiting post 311 at one end of the ear plate portion 110. The limiting post 311 is fixedly installed on the ear plate portion 110 by engaging with the notch 111 of the ear plate portion 110. The hovering member 220 is provided with a guide groove 221 for the limiting post 311 to extend into. The guide groove 221 has an arc-shaped groove structure and a narrowing opening 222 in the guide groove 221. During the rotation of the upper cover assembly 200 relative to the main housing 100, the hovering member 220 rotates with the upper cover assembly 200, causing relative rotation between the ear plate portion 110 and the hovering member 220. 311 moves along the guide groove 221. When the limiting post 311 moves to the constricted position 222, the limiting post 311 abuts against the wall of the guide groove 221 at the constricted position 222, restricting the hovering member 220 from rotating relative to the ear plate 110, thereby restricting the upper cover assembly 200 to a preset position and realizing its hovering function at the preset position. In addition, during the process of the upper cover assembly 200 rotating to open or close, the limiting post 311 abuts against the wall of the guide groove 221 at the constricted position 222. The frictional force that hinders the movement is generated at the constricted position 222, which can also play a certain buffering role, which helps to prevent the upper cover assembly 200 from rotating too fast and improves the safety of use.

[0047] In practical applications, the position of the constriction position 222 can be set according to the specific position where the upper cover assembly 200 needs to be suspended. In addition, multiple constriction positions 222 can be set to achieve multiple suspension positions. Besides the above structure, the suspension of the upper cover assembly 200 at the preset position can also be achieved by a magnetic attraction structure. For example, multiple magnetic attraction parts that can magnetically cooperate with the limiting post 311 are set in the guide groove 221. When the limiting post 311 moves past the magnetic attraction part, the limiting post 311 magnetically cooperates with the magnetic attraction part, thereby restricting the rotation of the upper cover assembly 200. The specific settings can be set according to the actual use needs.

[0048] In some embodiments, the cover assembly 200 includes a cover body 230, a connecting plate 240 and a cover plate 250. The cover body 230 and the connecting plate 240 are detachably connected. The cover plate 250 is bonded and fixed to the connecting plate 240 and can cover the connecting plate 240.

[0049] Understandably, such as Figure 1 , Figure 2 and Figure 10 As shown, the upper cover body 230, connecting plate 240, and upper cover plate 250 are arranged sequentially from bottom to top. An adhesive groove 242 is provided on the upper side of the connecting part. During use, adhesive can be placed in the adhesive groove 242, and the upper cover plate 250 is bonded and fixed to the connecting plate 240 through the adhesive groove 242, facilitating the bonding and fixation of the upper cover plate 250. The upper cover body 230 and the connecting plate 240 are detachably connected, allowing for easy disassembly, maintenance, and replacement of both the connecting plate 240 and the upper cover plate 250. The upper cover plate 250 can cover the connecting plate 240 from top to bottom, concealing the connecting structure and improving the aesthetics. In practical applications, the upper cover plate 250 can be a glass cover, and the specific structure of the upper cover body 230 and the connecting plate 240 can be customized according to actual usage requirements.

[0050] In some embodiments, the lower side of the upper cover body 230 is provided with a groove 203 and a first connecting part 231 is provided in the groove 203. A second connecting part 241 is correspondingly provided on the connecting plate 240. A threaded component is provided between the first connecting part 231 and the second connecting part 241 and is connected by the threaded component. The upper cover assembly 200 also includes a sealing strip 260, which is disposed in the groove 203 and can cover the threaded component.

[0051] Understandably, such as Figure 2 and Figure 10As shown, the lower side of the upper cover body 230 is provided with a ring-shaped groove 203. The groove 203 is provided with a plurality of first connecting parts 231. The connecting plate 240 is provided with a plurality of second connecting parts 241, which correspond one-to-one with the plurality of first connecting parts 231. A threaded component (not shown in the figure) is provided between the first connecting parts 231 and the second connecting parts 241 and is connected by the threaded component to realize the connection and fixation and detachability between the upper cover body 230 and the connecting plate 240. The lower side of the upper cover body 230 is provided with a sealing strip 260. The sealing strip 260 is provided in the groove 203 and can cover the threaded component, thereby better hiding the connection structure between the upper cover body 230 and the connecting plate 240, improving the aesthetics, and can achieve good sealing protection for the threaded component through the sealing strip 260, which helps to prevent the threaded component from being immersed in water, oxidizing and rusting, and facilitating use.

[0052] In practical applications, in addition to the above structure, the upper cover body 230 and the connecting plate 240 can also be connected by a snap-fit ​​structure. For example, multiple hooks are provided on the side ring of the connecting plate 240, and multiple snap-fit ​​grooves are provided on the upper cover body 230. The hooks are snapped into the snap-fit ​​grooves to realize the detachable connection between the upper cover body 230 and the connecting plate 240. The specific settings can be made according to the actual use needs.

[0053] In some embodiments, the upper part of the main housing 100 is provided with an upwardly extending buckle portion 120, the buckle portion 120 is provided with a locking groove 121, and the lower side of the upper cover assembly 200 is provided with a locking opening 204. The buckle portion 120 can extend into the connecting inner cavity 202 through the locking opening 204. The connecting inner cavity 202 is provided with a locking member 270, which can be inserted into the locking groove 121 to restrict the upper cover assembly 200 from rotating and opening relative to the main housing 100. The upper cover assembly 200 is provided with a button member 280, which can drive the locking member 270 to move and disengage from the locking groove 121.

[0054] Understandably, such as Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the upper left side of the main housing 100 has an upwardly extending buckle plate 120 with a locking groove 121. When the upper cover assembly 200 is rotated and closed on the upper side of the main housing 100, the buckle plate 120 extends into the connecting inner cavity 202 through the locking opening 204, and the locking member 270 is inserted into the locking groove 121 to restrict the upper cover assembly 200 from rotating and opening relative to the main housing 100, thus achieving relative locking between the upper cover assembly 200 and the main housing 100 and restricting the upper cover assembly 200 from rotating and opening. When it is necessary to rotate and open the upper cover assembly 200, the button 280 is operated, which drives the locking member 270 to move and disengage from the locking groove 121, thereby releasing the rotation restriction between the upper cover assembly 200 and the main housing 100 and unlocking the device. In actual applications, the specific structure and linkage method of the button 280 and the locking member 270 can be set according to actual usage needs, and will not be described in detail here, but will be explained in detail below.

[0055] In some embodiments, the locking member 270 is slidably disposed in the connecting inner cavity 202. A first elastic member 271 is provided on one side of the locking member 270. The first elastic member 271 acts on the locking member 270 and can drive the locking member 270 to move and insert into the locking groove 121. The button member 280 is disposed on the upper side of the upper cover assembly 200. A second elastic member 281 is provided on the lower side of the button member 280. The second elastic member 281 acts on the button member 280 and causes the button member 280 to have an upward tendency. A pushing slope 272 is provided on the locking member 270. A pushing part 282 is provided on the lower side of the button member 280. The pushing part 282 abuts against the pushing slope 272 and can push the locking member 270 to move away from the locking groove 121 through the pushing slope 272.

[0056] Understandably, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the upper cover body 230 has a sliding groove 232 in the connecting cavity 202. The side of the locking member 270 slides in the sliding groove 232 to achieve a sliding connection between the locking member 270 and the upper cover body 230, and to facilitate guiding and limiting its left and right movement. The right side of the locking member 270 is provided with a first elastic member 271, which is a spring. Its two ends abut against the locking member 270 and the upper cover body 230 respectively, so as to act on the locking member 270 to make it have a certain elasticity. There is a tendency to move to the left. When the buckle plate 120 is inserted into the connecting cavity 202, it is located on the left side of the locking member 270. Under the action of the first elastic member 271, the locking member 270 moves and inserts into the locking groove 121, realizing the relative locking between the upper cover assembly 200 and the main housing 100. A limit hook 273 is also provided on the right side of the locking member 270. When the locking member 270 is inserted into the locking groove 121, the limit hook 273 abuts against the upper cover body 230. This limits the travel of the locking member 270, improving reliability. The button member 280 is located on the upper side of the cover assembly 200. A second elastic member 281, which is a spring, is located on the lower side of the button member 280. Its two ends abut against the button member 280 and the cover body 230, respectively, giving the button member 280 an upward tendency. After pressing the button member 280 to move downward, the button member 280 can move upward and reset under the action of the second elastic member 281. A pushing part 282 is located on the lower side of the button member 280. A corresponding pushing slope 272 is provided on the locking member 270. The pushing part 282 abuts against the pushing slope 272. When unlocking, pressing the button member 280 to move downward causes the pushing part 282 to move downward and push the locking member 270 to the right through the pushing slope 272, so that it disengages from the locking groove 121, thus unlocking. The above structure is simple, reasonable, and easy to use.

[0057] In practical applications, in addition to the above structure, the button 280 can be set on the left side of the upper cover assembly 200 and can move left and right relative to the upper cover assembly 200. The locking member 270 can be moved left and right and is set in the connecting inner cavity 202. The button 280 and the locking member 270 are fixedly connected, so that when the button 280 is pressed to move left and right, it drives the locking member 270 to move left and right, so that the locking member 270 is inserted into or disengaged from the locking groove 121. An elastic member can be set to act on the locking member 270 or the button 280 to realize the movement and reset of both. The specific settings can be made according to the actual use needs.

[0058] In some embodiments, the main housing 100 is provided with a cleaning inner cavity 101 with an upper opening, and the upper cover assembly 200 is provided with a first exhaust channel 205 and a second exhaust channel 207. A bent flow channel 206 is provided between the first exhaust channel 205 and the second exhaust channel 207 and they are connected through the bent flow channel 206. The first exhaust channel 205 can communicate with the cleaning inner cavity 101, and the second exhaust channel 207 can communicate with the outside atmosphere.

[0059] Understandably, such as Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, when the upper cover assembly 200 rotates and closes on the upper side of the main housing 100, the upper cover assembly 200 covers the upper opening of the cleaning cavity 101. The first exhaust channel 205, the bent flow channel 206, and the second exhaust channel 207 are sequentially connected along the gas flow direction. The first exhaust channel 205 is connected to the cleaning cavity 101, and the second exhaust channel 207 is connected to the external atmosphere. This facilitates the discharge of hot air from the cleaning cavity when cleaning bowls and cups in the cleaning cavity 101. Furthermore, by setting the bent flow channel 206, the gas flow rate is slowed down, reducing the possibility of hot air being directly ejected and improving safety. In practical applications, the specific structure of the first exhaust channel 205, the bent flow channel 206, and the second exhaust channel 207 can be set according to actual usage needs.
